My invention relates to looms, and particularly to shuttle changing mechanism for looms using only one color or character of The object of my invention is to provide a shuttle changing mechanism adapted to be applied to and combined with looms, and

articularly the class, of looms referred to,

or changing a shuttle, preferably at either end of the loom, when the filling thereon has become ractically exhausted, or when a change 0? shuttle is desirable, without stopping the loom; the change of the shuttle being accomplished through mechanism put into operation by the weaver.

In my improvements I may provide mechanism for changing the shuttle at either end of the loom, or mechanism for changing the "shuttle at only one end of the loom. In case of changing the shuttle at both ends of the loom, the mechanism is substantially a duplicate of the mechanism for changing the shuttle at one end of the loom.

In my improvements, I provide on the end of the loom on which the shuttle is to be changed, a shuttle box with three separate cells, in line. with each other in a vertical plane. The top cell is for the spare or extra shuttle, which is inserted therein by the weaver through the {upper open end of the cell; the middle cell is for the active shuttle, which is continuously thrownacross the lay in the normal operation of the loom, and the lowest cell receives the shuttle which is to be changed and removed from the loom by the weaver.

I have only shown in the drawings detached parts of a loom with my improvements combined therewith sufficient to enable those skilled in the art to understand the construction and operation thereof.

Referring to the drawings :Figure 1- is a front view of portions of a loom, broken out through the center, and having my improvements combined therewith, for changing ashuttle at, both ends of the loom. Fig. 2 is, on' anenlargedscale, a section on line 2, 2,

Fig. 10 corresponds to Fig. 9, but shows some of the parts in a different In the tle cells embodying my improvements at each end of the loom, and mechanism for operating said cells. As the cells 'at each end of the loom are of the same construction, and the mechanisms for operating each set of cells are of the same construction and operation, a description of one will answer for both, and the same figures of reference will be used for similar parts.

In the accompanying drawings, 1 are the loom sides or end frames, 2 the breast beam, 3 the lay 3' the lay swords, 4 the reed, 5 the handrail, 6 the picker sticks, 7 the shuttle box ide frames on each end of the lay, and movable therewith, 8 'the rocker irons with which the picker sticks 6 and the lower I ends of the vertically moving shuttle box rods 9 are connected 1 the usual way, 10 the ive-way mechanisms connected with the s uttle box rods 9, and also connected at their lower ends with the levers which communicate vertical movement to the shuttle box rods. 1

11 is the bottom or cam shaft, driven in the usual way by gears, not shown, and connected,with the crank shaft; 12 by gears, not shown. I

13 is the crank connector to the lay 3.

Fig. 9 is a section, on line 9,

' pinion 14 which meshes with and drives in this instance an intermediate gear 15 on a stud 16. The gear 15 meshes with and drives a pinion 17 fast on a shaft 18 mounted in a suitable bearing 19 on the loom frame 1, see Fig. 3, and on a stand 20, forming -a part of, and secured to a stand 21, secured to the loom frame 1. On the shaft 18 is fast a mutilated gear 22, see Fig. 2, for operating the shuttle cells at the left hand end of the loom shown in Fig. 1. The mutilated gear 22 has in this instance an engaging tooth or projection 22 secured thereon by a screw 22", see Fig. 2. The engaging tooth 22 projects beyond the mutilated part of the gear 22. On the shaft 18 is in this instance a second mutilated gear 23 for operating the shuttle cells at the ri ht hand end of the loom, Fig. 1. The muti ated gear 23 has an engaging tooth or projection 23" thereon, corresponding to the engaging tooth 22. The tooth or projection 22 on the mutilated gear 22 is adapted to engage a projection 24 extending out from a hub 24, and forming a clutch member, see Fi 2, and loosely mounted on a stationary sha 25, to move longitudinally thereon. The shaft 25 is secured to the stands 20 and 21'.

The projection 23 on the mutilated gear 23 is adapted to-engage a projection 26f extending out from a hub 26, see Fig. 3, and forming a clutch member, and loosely mounted on the shaft 25 to move longitudinally thereon.

A rock shaft 27 is mounted in suitable bearings on the stand 20, see Fig. 2, and has fast on its inner end', the hub 28 of a fork or clutch lever 28 having pins thereon'adapted to enter the annular groove 24" in the hub 24, and acts to move said hub longitudinally on the shaft 25. The outer end of the rock shaft 27 has fast thereon the hub 29 of an arm 29, see Fig. 2. A corresponding fork or clutch lever 30, fast on a rock shaft 31, see Fig. 3, has pins thereon to enter the annular groove 26!- in the hub 26, and acts to movesaid hub longitudinally on the shaft 25. The outer end of the rock shaft 31 has fast there'on the hub. 32 ofan arm 32, see Fig. 3.-

A helical tension spring 33," attached at each end to the lever or arms 29' and: 32, acts to move the upper ends of said arms I towards each other to rock the shafts 27 and clutch levers 28 and 30 in their normal inoperative position.

A link or bar 34 is connected with both of the levers 29 and 32, in this instance by pins 29 and 32" on said levers extending into two elongated slots 34 in said bar or link 34. The bar or link 34 is also pivotally connected in this-instance at its inner end with an arm 35 fast on a rock shaft 36 mounted at its rear end in a stand 37, secured to the frame 21. The front end of the rock shaft "36 has an arm38 fast thereon, see Fig. 1, which is pivotally connected throu h a con,

nector 39 with one arm of an ang e or hell crank lever 40, in this instance pivotally mounted on a stud 40, secured to the front side of the loom frame; the other arm of the angle or bell crank lever 40 has secured thereto one end of a rod 41, which is supported and moves longitudinally in guide eyes 42' 'on.stands 42, secured in this instance to the front of the breast beam,-see

'rojection 24 on the hub 24, see Fig. 9.

he lug 24" extending into the opening 43' on the ear 43 attaches said gear to the hub 24, an causes 1t to revolve with said hub,

when said hub is revolved by the mutilated gear 22. The cam 44 has a cam groove 44, shown by broken lines in- Fi 2, lnto which extends ain or roll 45 on '3, ever 45, fast on a rock sha t 46, which is mounted in suitable bearings and extends transversely through the loom. Said rock shaft 46 is connected at its other end through the give-way mechanism 10, with the shuttle box rod 9 of =theshuttle box having three cells, shown at the left in Fig. 1. The cam 44 has in this instance a recess 44 in-its periphery, to receive a roll 47 on an arm 48, pivoted on a stud 48, and actuated by a helical tension spring 49, at- .tached at one end to a projection 48 on said arm 48, and at its other end to a rojection-50 on a stand 50, see Fig. -2. e roll 47 acts as a yielding lock for the cam 44 and gear 43, to hold them in position after each complete revolution thereof. A second mu tilated gear 51 see Fig. 3, corresponding tothe gear 43 is loose on the shaft 25, and has secured thereto, by a bolt and slot connection, not shown, a cam 52 corresponding to the cam 44. The mutilated gear 51 is connected with thehub or clutch 26, in the same manner as described above in connection with the mutilated gear 43 andthe hub or' clutch 24. The cam 52 has a cam groove therein to receive a pin or roll on the inner end of the box lever 53, which has a hub loosely mounted on the shaft 46, and the outer end of the box lever 53 is connected-with the lowerend of the give-way mechanism 10, attached to the vertically moving shuttle box rod9, see Fig. 2.

when said clutch member is moved into position to be engaged by said engaging arm. ThlS mechanism in this instance consists of a latch 56, pivotally mounted on a pin 57 on a stand 58 bolted to the frame 20. A spring59 attached at one end to the latch 56,

and at its other end to a stationary projection 58 1 on the stand 58, acts to raise the outer end of said latch.

' When the clutch member 24 is out of clutchwith the engaging arm 22 on the mutilated gear 22, as shown in Fi 9, the projection 24 on the clutch 24 willengage with and: move down the latch 56, and also engagethe projecting end 58 of the stand 58,to

' prevent any further rotation of the clutch.

When theclutch member 24 is moved on the shaft 25, to bring the projection 24 in the path, of the engaging arm 22 on the gear 22, as shown in Fig. 10, the rojection 241 on the clutch member 24 will be moved out of the path of the latch 56, and allow the spring 59 to act tomove up said latch 56, and cause the end thereof to extend back of the projection 24 ,on-the clutch member 24, as shown ,in Fig, 10, to hold said clutch member'24 in its operative position, until the movement of the mutilated gear 22 rotates the clutch member 24, and moves it out of engagement with the latch 56.

I will now describe theshuttle box, in this instance at. each end of the loom in Fig. 1, and having three cells.

The middle, or intermediate cell 60 is referably of the ordinary construction of as ut tle box cell in shifting shuttle boxes, and has a shuttle binder 61-, and 'a binder spring 62, in the usual way. The top cell 63 is open on top, asshown in Fi 4, to allow of the ready insertion of a shutt e therein by the weaver,

which'jshuttle is the extra or spare shuttle 64, to be-s'ubstituted for' the shuttle which is to vbe exchan ed on account of practical exhaustion of filing, or for any other reason. The top cell 63 has a binder 65 and binder s ring 66, preferably of usual construction.

he bottom cell 67 which receives the shut -tle having the filling practically exhausted,

mechanism being or the shuttle which is to be exchanged, is preferably made as shown in Fig. 5, with its inner end in line with the race-way of the lay, and outwardly inclined from its innerend, to cause the shuttle therein to extend beyond and out of line with the other cells.

A stationary stop 68 is secured on the shuttle guide frame 7, see Fig. 5, in line with the race-way of the lay, against which the shuttle entering the bottom cell 67, when it is in line, with the race-way, strikes. The bottom cell 67 is providedwith a binder 69, which preferably 18 moved inwardly, to bear against the shuttle 64, see Fig. 5, by a spring actuated rod 70, secured at its outer end in an ear 69, and extending at its inner end loosely through an opening in a boss 71 on a projection 67 on the front side of the inner end of the bottom cell 67, see Fig. '5.

A helical expansion spring 72 encircles the rod70, and bears at one end against the boss 71, and at its other end a ainst a nut 73, adjustable on the threaded outer end of the rod 70. 1

'InFigs. 6 and 7 are shown a modified construction of the shuttlecells above described.

In said Figs. 6 and- 7, the'upper shuttle cell, for the extra shuttle is open in front aswell as on the top, and has a short binder 74, which in this instance is.pivotally attached at its outer end to a plate 7 5,- secured to the outer front side of the cell, and its inner end, which extends to about the middle point of the cell, is providediwith an upwardly extending projection 74-, which is adapted to be engaged by the weaver, to move out the binder and insert a shuttle. A short binder spring 74" is used in connection with the binder 74. i

The bottom shuttle cell'of the shuttle cells shown in Figs. 6 and 7 is of substantially the same construction as the bottom cell 67, shown in Fig. 5, except that the binder 69 is actuated by a flat leaf spring 76, secured at one end to the binder 69, and extending at its other end under the binder retaining rod 77. f

From the above description in connection with the drawings, the operation of my improvements will be readily understood by those skilled in the art. a

A normal position of the shuttle cells at each end of the loom, is with the middlecell in line with the race-wa spare or extra shuttle will always be in the top shuttle 0611. When, in the normal operation of the loom, with the several parts in the position shown in Figs; 1, '2, and 3,. the weaver notices that the filling in the running shuttle is practically exhausted, or for any other reason it is desired to change the running shuttle and substitute'another shuttle, the weaver moves the rod 41 to the right or to the left, in case there are two sets of shuttle cells, one at each end of the loom, a0-

of the lay, and a cording to whether the change is to be made I on the right hand end, or the left hand end of gears to the pinion 14 onthe bottom shaft 11,

will cause the rotation of the hub or clutch 24, and through the engagement'of said clutch with the gear 43, Wlll causethe rotation of said gear 43, and the cam 44 attached thereto, and through the cam lever and give-way mechanism'10, the box rod 9 and the. shuttle cells supported thereon, will be moved up to bring the lowest cell 67 on a line with the race-way of the lay, to receive the shuttle to be exchanged; the continued rotation of the cam 44 will, through cam I lever 45, lower the cells to bring the top cell 63 in line with'the race-way of the lay, so

that the spare shuttle thereinmay be picked across the loom into a shuttle cell on the other end of the loom, to take the place of the one exchanged. After theshuttle has been picked, the continued revolution ofthe cam 44, to make one complete-revolution thereof, will, through cam lever 45, move up the shuttle cells to bring the middle cell v of the three shuttle cells'in line with the raceway, to receive the new shuttlefrom the other end of the loom, and the loom will continue to operate with the middle shuttle cells on a line with the race-way. The cam 44 having made one complete revolution, theroll 47 will enter the recess 44" in theperiphery of the cam44, to yieldingly hold the cam. On

1 the movement of the hub or clutch 24 .into

the path of the projection 22 bn the mutilated gear 22, the latch. 56 drops in back of the engaging arm 24 on the hub 24, to hold it in the path of the projection 22 on the gear 22 as above described. 'Assoon as the operation of changing theshuttle and substituting a new shuttle has been completed, the sprin 3 3 acts, through connections to .the clutc 24, to move it on the shaft 25 into its inoperative 7 position, with its engaging arm 24' out of the path of the projection 22 on the mutilated gear 22. The arin 24' on the clutch 24, engaging with the stop 58" on thestand 58, see Fig. 9, stops the rotation of the clutch, and also oftlie gear 43, and cam 44.

In case a chan e of shuttle is to be made 4 'on the right han end of the lodm 'shown in Fi .31, the weaver moves the rod41 to the rig t, and through the intermediate connections' to the clutch 26, said clutch is moved into the path of the'projection or engaging arm 23 on the mutilated revolving gear 23, and-the revolution of said gear 23 revolves the hub or clutch 26, and the mutilated gear 51 with which it is connected, and also the cam 52 connected with said gear 51, and through the cam lever 53 and give-way mechanism 10, and the shuttle box rod 9, the. shuttle cells on the right hand end of the loom, shown in Fig. 1, are operated in the same manner as above described in connection with the shuttle cells on the left hand end of the loom.

It'vvill be understood, that as soon as the cells have been returned to their normal position, the weaver will remove the shuttle from the bottom cell, and will insert a new shuttle in the top cell, for the extra or spare shuttle. With my improvements I obtain a continuous running loom .with a shuttle changing mechanism which may be put into 0 eration at either end of the loom, and allow t e weaver to change the shuttle at either end of the loom and substitute a new shuttle, without stopping the loom.

It will be understood that the details of construction of my imgxrovements maybe yaried if desired. The s uttle changing cells may be on only one end of the loom, in which case the opposite end of the loom will referably' have a single shuttle box or ce 1, and one-half of the mechanism for operating the shuttle cells shown in the drawings will be dis ensed with, to wit,the mutilated gear 23 aving a rojection 23 thereon, the clutch 24, the muti atedgear 43, the cam 44, mechanism for locking said cam, and mechanism for locking the clutch 24, and mechanism for moving the clutch 24.
